[Bug 2027826] Re: Mantic Cloud-Images on amd64 Fail To Preseed Snaps

[Dan Bungert]

@John - would you expect lxd to be part of the cloud-image.snaps
germinate output?

In this log, with some set -x,
https://launchpadlibrarian.net/677345865/buildlog_ubuntu_mantic_amd64_test_BUILDING.txt.gz

config/seeded-snaps appears to be empty.  But looking at the seed git
history I don't see why this would have changed?  I'm confused.

Title:
  Mantic Cloud-Images on amd64 Fail To Preseed Snaps

Status in cloud-images:
  New
Status in livecd-rootfs package in Ubuntu:
  New

Bug description:
  Starting on June 19th, Mantic Cloud Images (in development) on amd64
  are failing to pre-seed snaps provided in Seeds. This is observable by
  taking any Mantic Cloud Server (not minimal) image and checking if
  `lxd` is installed.

  Troubleshooting steps so far:

  1. using `ubuntu-bartender`[0] and local checkouts, I bisected
  `livecd-rootfs`, starting from commits before June 19th.
  Unfortunately, due to various other build issues, I was not able to
  successfully find a commit. Commits <= tag 2.849 fail to build, and
  commits after fail to have snaps preseeded. More work can be done here
  to find a successfully building commit (I did not go a back through
  the entire history, only to tag 2.848)

  2. I attempted a revert of tag 2.890 specific code, which landed
  around the time failures to pre-seed began. Reverting that specific
  code did not result in fixing the issue.

  3. a build and check of the log at `lb_chroot_cache save` will show
  the issue. in a successful build, the apt cache is updated and snaps
  are preseeded.
